Which Is Best For You?

If you’re sitting here comparing options, you’ve already taken a big step. You’re ready to get started, you just need some direction. At this stage, it’s important to take yourself into account. Some people are better off in big gyms, others at personal training gyms. In our experience, the people that do best in big box gyms have a few common characteristics. They aren’t intimidated being around endless rows of exercise machines or the 20-year-old gym-goers who seem to live on them. They also don’t need any help being accountable because they know they’re going to show up. In our experience, these people make up a very small percentage of the adult population.

A gym like this is $10 to $25 a month. Much cheaper than your typical personal training gym. But most people don’t Google “personal training” because of the price… they’re trying to figure out if it will help them finally make this stick. Because most people have already tried the cheap gym. They’ve already had the membership they barely used. The sauna and smoothie bar are nice amenities, but they don’t keep you showing up the way a scheduled session with a coach will.

Or maybe you have a home gym. This can be even trickier because you tell yourself you’ll do it after the laundry… but then you realize you need to do the dishes. Then after that you get a work email. And before you know it, it’s 9pm and you’re on the couch telling yourself you’ll definitely do it tomorrow. And the worst part isn’t even the missed workout, it’s how you feel when you know you’re not keeping the appointments you scheduled with yourself. As if those appointments aren’t as important as all the other ones.

People who come to us aren’t confused about what a gym is. They’re tired of making commitments that they know they won’t keep. What they learn they need is an appointment with a coach waiting for them… a plan that’s built for their body, and a place where they know exactly what to do from the moment they walk in. That’s a completely different thing from a gym membership or a basement workout.

The Real Cost of a $25/Month Gym Membership

Big box gyms like Planet Fitness look like a great deal on paper. Around ten to twenty-five bucks a month, long hours, tons of equipment. For the right person, that’s a great deal. But for most adults who haven’t had a consistent fitness routine in years, it’s not the best fit.

A lot of our members come in having tried a big box gym before us. Here’s what they usually experience… First, they start excited, buy some new shoes and workout clothes, and a water bottle that says “keep glugging” on it. Week one, they’re there four or five days during the work week. But week two, life does what it does and gets busy… and then it drops to two. Week three, they’re still feeling overwhelmed by all the equipment and have just settled into doing a couple miles on a treadmill. By week four, they haven’t seen much progress and don’t show. And just like that, one month in, the excitement they initially felt is gone and they’ve quit, without actually canceling their membership. Then they pay $25 a month for the next year or so even though they keep meaning to cancel but don’t, because canceling means that they won’t go back… and they really do want to make fitness work.

A lot of emotions come with this experience that make it hard to get back into a fitness routine. You might feel some shame it didn’t work out, and you might feel afraid to fall short again. But it’s really not your fault. Working out is a skill. And just like any other skill, having a teacher increases your chances of success dramatically. They meet you where you’re at and tell you how often to work out, how to use the equipment, what good form looks like, how to stay safe… and most importantly, they keep you accountable.

At the end of the day, $25 a month is very little money and it makes sense that it’s a lot of people’s first option for a gym membership. But quick thought experiment… imagine I could give you a magic potion and as soon as you drank it you’d reach your goals. You’d feel more confident, drop 10 pounds, lose a few pant sizes, wouldn’t be tired climbing the stairs or hanging out with the kids. How much money would you pay for it? I’m sure it would be more than $25.

What Personal Training Actually Costs — And What You’re Getting

One-on-one personal training in the South Shore area runs between $150 and $200 an hour. Two to three sessions a week… which is where most people have the best results… will run you $300 to $600 a week. For most people, that’s not sustainable long term. Sustainability is very important. Reaching your fitness goals is great, but only if they are permanent.

But here’s a way to think about the cost that is easy to skip over… and you’re going to need to forget the magic potion thought experiment from the previous section. The truth is that you need to think about investing in your health and fitness as being proactive. It’s a cost you pay upfront so that you don’t end up paying reactively on the other side. Reactive is always more expensive. Medical bills don’t give you a monthly payment plan that fits your budget. You don’t get to negotiate with hospital bills from being sick or driven in an ambulance. The investment you make now in getting stronger, building bone density, improving your metabolic health… that’s money that doesn’t get spent later on things you really don’t want to be spending money on.

That’s where small group comes in. At Big Day Fitness, small group personal training runs about $41 a session… a fraction of the cost of one-on-one. You still get a customized program, a coach who knows your history and injuries, and gives real attention to your form. You’re just sharing the space with a few other people, which most members end up liking more than they expected. It’s a number people can actually keep up for years — and that’s the whole point, because results only come when you stay consistent.

And to help with that proactive investment, Big Day Fitness is an approved HSA/FSA facility. That means many of our members are able to use their pre-tax healthcare savings funds to cover part of their membership. If you have an HSA or FSA account, and you are eligible, that changes the math significantly.

Who Each Option Is Actually Right For

When a regular gym membership makes sense

We’re always very straight. A place like Planet Fitness is genuinely a good fit for some people. If you already have a solid fitness background, you know how to train safely on your own, you have a plan you trust, and what you’re really looking for is access to equipment at a low monthly cost, that option makes sense for you.

But it is not for most people. And it’s pretty much never the person over 40 who’s been out of a routine for years and is trying to figure out where to start.

Who Big Day Fitness is built for

We are the right fit if any of these sound like you:

  • You’re starting from zero and have no idea what to do once you walk into a gym.
  • You’ve had bad experiences before… got hurt, felt out of place, or fell off after a few weeks.
  • You’re dealing with an injury, chronic pain, or something your doctor told you to be careful with.
  • You know you need accountability… because without someone expecting you to show up to your appointment, you won’t.
  • You want to train with people your age, going through the same things. Not to feel like the oldest person in a room full of 22-year-olds.
  • You want a coach who actually knows you.

Our small group sessions are the sweet spot for most of our members. You get a custom program, a coach who’s fully present, and the energy of training alongside other people… which makes a bigger difference than most people expect. The groups are capped at six people per trainer and you are not anonymous here.

Rather Just Come See It for Yourself?

Your first step is a free 45-minute strategy session with a coach — a relaxed conversation about your goals, your history, and what would actually work for you. No commitment. No pressure.

What Results to Expect

There’s no exact measurement for what it feels like to be strong in your own life. It’s different for everyone.

For some it’s getting on and off the floor without looking for something to grab onto, and pain-free trips up and down the stairs without noticing your knees.

For others it’s skiing a full day and having fresh legs on run three… or carrying your luggage through an airport without your back flaring up… and then tossing it in an overhead compartment by yourself.

These might look like small things, but when they’re hard, they’re all you think about. And when they’re easy again, your whole life opens back up.

One of our members, Sue, came to us after months of not being able to ride horses, which was something she’d done professionally for years. Her lower back had gotten so temperamental that she’d stopped completely, and she was devastated. After six or seven months with us, her legs and core got stronger, her back pain disappeared, and she got back on the horse. Pun intended. Her riding instructor told her that her posture was actually better than before the injury. She was pumped.

But she also mentioned something smaller that really struck home with us. She said that before she started strength training at Big Day, she thought twice before leaning forward to brush her teeth. Every single morning, she’d brace herself because she was afraid of throwing her back out on something that basic. Once she got strong enough, and the back pain went away… that thought stopped crossing her mind. She can brush her teeth now without overthinking.

That’s the return on investment nobody puts in the comparison chart. And there’s no dollar amount you put on that.
